Abstract A new D-shaped tellurite photonic crystal fiber sensor based on the four-wave mixing (FWM) effect with surface plasmon resonance (SPR) is designed and optimized. The substrate of (D-PCF) glass, polished plated gold film hydrogen gas-sensitive film. An air hole inner cladding, which methane film, selected as second sensing channel to simultaneously measure concentration methane. Based m...
In this paper, design and simulation of a new highly sensitive gas sensor based on a hybrid photonic crystal (PC) structure, containing negative and positive refractive index sections, is presented. It has been shown that using a PC with negative refraction in the first section, the transmitted power is concentrated on the entrance of the sensing channel, and the transmission of the proposed se...
Proton-exchange membrane (PEM) fuel cells are being developed for both automotive (motive and/or auxiliary) and stationary (residential) power applications. Solid oxide fuel cells (SOFCs) also are being pursued for a number of power generation applications, including stationary (residential and utility), and automotive (auxiliary) power sources. For both of these types of fuel cells, the use of...
Objective: The purpose of this study was to develop a novel colorimetric system for direct detection of hydrogen sulfide on the tongue dorsum from subjects with complaints of halitosis. Method: An assay system comprised of a cotton swab impregnated with zinc sulfate, attached chromatography paper, stabilizing solution, and coloring reagents for the methylene blue technique was developed. Using ...
In this research, ZnO nanorods were utilized as gas sensor materials for detecting toluene vapour and hydrogen prior to following the use of Zeolitic imidazolate frameworks-8 (ZIF-8) filter. On porous Al2O3, ZIF-8 was deposited thickness 200 nm. Scanning electron microscope (SEM), XRD, sensing tests used examine material characteristics regarding ZnO. Thin films' sensitivity selectivity differe...
